There's something really moving about standing in the centre of London Wall's Roman ruins and looking up at the city that has grown around it. Thinking about our past, present and future simultaneously. More than 2000 years have passed since the Romans created our city, and while much has changed there's still so much consistency in how our society exists, both the beauty and the flaws. As a civilisation, how far have things really shifted?

“Am I myself?” At the tangled centre of Shakespeare’s comedy of two pairs of identical twins, servant Dromio asks the question on which everything else hangs. The delivery is exasperated, the context bantering, but the words are the flimsy door onto an existential void this early play constantly threatens to tumble into.

How can we know ourselves if others do not? Is it enough to be ourselves, or must we also enact and perform those roles? What if society casts us in another?

“Take Jazz Seriously,” wrote Maurice Ravel after his American trip in 1928. This past week of the 2021 EFG London Jazz Festival has seen that advice itself being taken seriously, with a bunching of projects and premieres. Jazz musicians have been welcomed in to work with London orchestras. The fruition of months of preparatory work has been on show.

Where do you draw – how do you draw? – a credible line between jazz and “classical” music in 20th-century America? With the reliably boundary-busting Britten Sinfonia, trumpeter Alison Balsom mixed and matched works from different formal lineages in her packed programme at Milton Court, “An American Rhapsody”.

Isamu Noguchi may not be a household name, yet one strand of his work is incredibly familiar. In 1951 he visited a lamp factory in Gifu, a Japanese city famous for its paper lanterns. This prompted him to design the lampshades that, for decades, have adorned nearly every student’s bedsit.

Whatever the upsets and uncertainties of this musical season, the return of choral works at full scale and full power has been an unalloyed joy. And sheer, exhilarated, heaven-storming joy branded the Academy of Ancient Music’s reading of Haydn’s The Creation in the Barbican Hall on Tuesday night.

If a standard-sized recital hall can be a lonely place for a solo violinist, playing an auditorium of Barbican dimensions must feel like crossing a desert under pitiless spotlight sun. Happily, Nicola Benedetti’s prowess as a communicator means that she made those trackless wastes shrink into a shared garden where she, and we, explored her instrument’s many kinds of bloom. Defiantly, a solitary figure in red on the enormous stage, she began her recital with Bach’s D minor partita – and the mighty, earth-moving Chaconne which completes it.

For most Bruckner fans, the multiple editions and revisions of his symphonies are a problem. But Simon Rattle sees it differently; for him every edition offers more music to explore. That was the thinking behind this programme, presenting the Fourth Symphony in one and a half versions, a “discarded” scherzo and finale in the first half, and a complete version in the second.

A young film director writes a script based on his father’s life story and invites his dad to play the part. It’s an interesting gambit, given that the son, Jorge Thielen Armand left Venezuela with his mother at the age of 15 and has not returned since. His father stayed behind, so their relationship has stalled. Can it be reignited?

"Times have changed", we're informed in the cascadingly witty title number of the Cole Porter musical Anything Goes, now in revival at the Barbican and bringing with it a pandemic-clearing tsunami of joy.
